Updating my Shopping channel on 4.1u which method please

OK, I was using WiiSCU version WiiSCU v0.22 because it said on the site for anyone using 4.1 to use the first version.

I ran it, and it appeared t oinstall fine but my shoppping channel is still telling me to get the update through the firmware... do I now have to use the latest version of WiiSCU? Or should i use a idfferent method like Marc's 4.2 Shop Channel Updater?

It makes sense to think of it like this: It said 4.2 because its simply updating the shop chan to what would come with 4.2... not that its only an updater used on firmware 4.2 correct?
